Video Codec Profiles and Levels: A Guide for Video Creators
When you’re creating a video, one of the most important decisions you’ll make is the video codec you’ll use. The codec will determine the quality and size of your video, as well as the compatibility with different devices.
Video codecs are divided into profiles and levels. Profiles define the features that are supported by a codec, while levels define the maximum quality and size of a video encoded with that profile.
What are Video Codec Profiles?
Video codec profiles define the features that are supported by a codec. This includes things like the type of frames that are supported, the resolution of the video, and the chroma subsampling.
There are a number of different video codec profiles available, each with its own strengths and weaknesses. Some of the most common profiles include:
Main Profile: This is the most common profile and is supported by most devices. It supports a wide range of resolutions and chroma subsamplings.
High Profile: This profile offers higher quality than the Main Profile, but it is not supported by as many devices.
High 10 Profile: This profile supports 10-bit color, which can provide even higher quality than the High Profile.
What are Video Codec Levels?
Video codec levels define the maximum quality and size of a video encoded with a particular profile. This is determined by factors such as the maximum bitrate and the maximum frame rate.
There are a number of different video codec levels available, each with its own quality and size requirements. Some of the most common levels include:
Level 3: This is the lowest level and supports a maximum bitrate of 10,000 kbps.
Level 4: This level supports a maximum bitrate of 20,000 kbps.
Level 5: This level supports a maximum bitrate of 40,000 kbps.

Choosing the Right Profile and Level
The best way to choose the right profile and level for your video depends on a number of factors, including:
The desired quality of the video.
The target audience.
The devices that the video will be played on.
If you’re creating a video for a wide audience, then you’ll want to choose a profile and level that is supported by most devices. If you’re creating a video for a specific audience, then you may be able to choose a higher quality profile and level.
